JOHN E. MULDROW, OF LYNOHBURG, SOUTH CAROLINA.

IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 186,152, dated January9,1877; application filed July 20, 1876.

companying drawings, and to the letters of reference marked thereon,which form a part of this specification.

The nature of my invention consists in the construction and arrangementof a horsepower for cotton-gins, as will be hereinafter more fully setforth.

In the annexed drawing, Figure 1 is a plan view of my horse-power. Fig.2 is a vertical section of the same through the line a w of Fig. l.

Areprcsents a suitable frame-work, in which is a vertical shaft orroller, B, turning upon pivots, and provided with a sweep, O, for theattachment of the team. On the shaft or roller B is secured a largehorizontal wheel or drum, D, on the top of which is fastened an annularband,'E-, of india-rubber, canvas, or other suitable material. Frepresents a horizontal shaft, also turning upon pivots, on which issecured a fly-wheel, G, and also a band wheel, H. There is furthersecured upon this shaftan india-rubber drum, I, or a wooden drum coveredwith india-rubber, which presses on the rubber band E of the large WheelD. At the end of the drum I is a circumferential flange or head, J, theside of which extends over and presses against the edge or rim of thewheel D.

The shaft F has its pivot hearings in hangers V V. which are madeadjustable, so that the shaft can be raised or lowered to bring the drumI and wheel D in proper contact with each other.

K represents another horizontal shaft, which also turns on pivotsarranged in fixed hangers. On this shaft-is a fly-wheel, L, and also aband-wheel, M, for a band to pass around and connect with the cotton-ginor other machinery. There-is also on this shaft a drum,

N, which connects and is turned by the band 0 passing around theband-wheel H.

When the horse pulls the sweep O the whole power is put in motion. Thispower may be run also with a horizontal band-wheel. To this end Iprovide a vertical shaft, P, which turns on pivots, and is arranged in asuitable frame-work attached to the main frame A. On this shaft is anindia-rubber drum, R, which presses against the rim of the large WheelD. On the shaft P, up in the ginhouse, isa horizontal band-wheel, S,with a band passing around it, and connecting with the cotton-gin orother machinery.

Between the band-wheel S and the cottongin are two rollers, T and U,fixed and set in proper frames. The roller T is set at an angle, but theroller U is perpendicular, and they are both intended for tightening theband, giving it the proper twist, and holding it to its place on thegin-hub, and also on the band-wheel.

By my invention I can run two gins at the same time by using bothwheels, or I can use either and run one gin only.

This power is simple in construction, cheap, and durable, and takesconsiderably less horsepower than those now in use.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1'. In a horse-power, the combination of the vertical shaft or roller B,with horizontal wheel D, having rubber band E, the shaft F, hung inadjustable hangers V V, drum I, circumferential flange J, shaft K,pulleys H M N, and fly-wheels G L, all arranged substantially as and forthe purposes herein set forth.

2. In a horse-power, the horizontal wheel D E, horizontal shaft F, drumI, vertical shaft P, and drum R, all constructed and arrangedsubstantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
